Molded tantalum, 0.68 µF at 35 V
KYOCERA AVX TAJB684K035RNJ is a molded tantalum capacitor in the TAJ series, delivering 0.68 µF capacitance with ±10% tolerance at a 35 V rated voltage.
The molded case provides mechanical robustness and moisture resistance compared to uncoated chips, which matters in conformal-coated assemblies or high-vibration environments.
Size code B corresponds to the 1411 (3528 Metric) / 1210 footprint – 3.50 mm x 2.80 mm body, 2.10 mm seated height. Surface-mount on tape and reel – the 0.68 µF value is commonly used for bulk decoupling on 3.3 V or 5 V rails where the 35 V rating provides ample derating margin.
